Abstract
A system for communication between BMSs of a battery pack including a plurality of BMSs connected to a parallel communication network, and a plurality of slave BMSs allocated with different communication identifiers, each having a variable field; and a master BMS for allocating a communication identifier to each of the plurality of slave BMSs through the parallel communication network, changing a priority determination value allocated to the variable field according to a predetermined condition, and performing communication with the plurality of slave BMSs based on the communication identifier.
Claims12
A system for communication between BMSs of a battery pack that includes a plurality of BMSs connected to a parallel communication network, the system comprising:
- a plurality of slave BMSs allocated with different communication identifiers, each having a variable field;
- and
- a master BMS configured to:
- allocate a communication identifier to each of the plurality of slave BMSs through the parallel communication network,
- change a priority determination value allocated to the variable field of each slave BMS according to a predetermined condition, and
- perform communication with the plurality of slave BMSs based on the communication identifier.
A method for communication between BMSs of a battery pack that includes a plurality of BMSs connected to a parallel communication network, the method comprising:
- allocating a communication identifier having a variable field to each of a plurality of slave BMSs through the parallel communication network;
- changing a priority determination value allocated to the variable field of each slave BMS according to a predetermined condition;
- and
- allowing the plurality of slave BMSs and a master BMS to communication with each other based on the communication identifier.
